Author Topic: inflatable screen's? Ken McFall Jedi Master Film Handler Posts: 615 From: Haringey, London. Registered: Apr 2001 posted 04-13-2004 09:35 AM                     Hi Peter, yes same screen I'm sure and the same people putting it up? I have some pictures somewhere of the Trafalgar Square job with the front guy ropes almost vertical.... I'd done a few jobs as you know and when it went well the whole thing looked great. Its all down to using the right people who will follow the instructions for safe use! or is that me just being silly? Looking back it was all being done on the cheap and they got away with it.... one day it will all go horribly wrong and someone will get hurt. Then it'll be pass the buck time, but nothing new there then. [ 04-14-2004, 06:36 PM: Message edited by: Ken McFall ]  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

The four blocks on each corner each weigh 1 tonne  |  IP: Logged Mike Fitzgerald Expert Film Handler Posts: 224 From: Castle Hayne, NC, USA Registered: Jun 2002 posted 04-13-2004 10:59 PM                     So I guess my question would be how big a container would you need if you wanted to use water as a ballast on the screen. The containers could be filled with 1 ton of water. A fire dept water pummper could be used to fill them each time.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 04-14-2004 03:47 PM                        Water weighs approximately 8.3 pounds per gallon.

Hardly a fire truck needed. Just a decent hose line under good pressure. Actually, during Showest, I had the pleasant opportunity of speaking at length with Christian from the German manufacturer of Airscreen, which is distrib'd by Harkness Hall. From what I've seen, they're an excellent solution to temporary screens in an outdoor setting. They beat the heck out of scaffold systems. To be sure, if what's needed is a semi-permanent installation, to stay in place for any real length of time, then a scaffold system, with a solidly backed screen, (to avoid cupping the sheet in any kind of breeze,)is likely necessary. But if it's for a single show or even a three or five day show, the airscreen is worth looking into. For multiple days, at the end of the evening's show, simply deflate and start over again the following day by simply inflating the frame.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 04-14-2004 04:09 PM                        quote: John is that 8.3lbs per gallon fresh spring water or the water that can't be used from redeveoloping soundtracks Fresh water, of course. You wouldn't want to drink the water used to wash off soundtrack developer until it went through a municiple sewage treatment plant. I wonder what they do with "heavy water" from nuclear reactors?  |  IP: Logged Ken McFall Jedi Master Film Handler Posts: 615 From: Haringey, London. Registered: Apr 2001 posted 04-14-2004 06:24 PM                     Ray the system is ideal for use in the way you describe. Thats how we used it, left laid out overnight and then reflated the next day. But for safe use it needs to be used sensibly. There is also a rear sheet that goes on the rear side that would reduce the sail effect on the actual screen surface and help keep it flat, we didn't have one so the screen did distort quite a lot. It needs at least four, preferably six, people to raise and lower the whole thing. At the end of the event it can be rolled up with the screen in place, if its going to be used soon after, but its a dead weight and very difficult to man handle. Getting it back into the van was a real struggle. Some thought needs to be given to an easier way to move it around. Here are some pics of the Trafalgar Square setup.... note the front guy ropes are FAR too close to provide proper safe stability.  |  IP: Logged Daryl C. W.

Pytlak I wonder what they do with "heavy water" from nuclear reactors? Why they reuse it of course! Heavy water (D-sub2,0) has a life span longer than nuclear facilities and can be reused. No need to dispose of it. As far as I know, the 32 CANDU reactors in use worldwide are the only nuclear reactors used for electrical generation that use heavy water. The CANDU design is more efficient than light water reactors, using 15% less fuel for the same output. They are also online refuelable (other reactors must be shut down) and can use natural uranium, eliminating the need for an expensive enrichment process.  |  IP: Logged Peter Hall Master Film Handler Posts: 314 From: London, UK Registered: Dec 2000 posted 04-15-2004 05:43 AM                        Does the banner under the screen refer to the long-bearded rigging crew ? Is a comedy of errors ?  |  IP: Logged Phil Blake Jedi Master Film Handler Posts: 558 From: esperance western australia Registered: Nov 2003 posted 04-15-2004 07:02 AM                        These inflateable screens look like a real silly thing, particularly on the australian coast when the winds are rather strong at times. One great portable screen is the side of a truck pantech (white one) , there is a guy over here running a travelling show , uses the truck and trailer to cart equipment , the side of the truck is the screen and the trailer is the bio box , I am sure a semi trailer pan at 45' by 10' would make a far more stable screen .  |  IP: Logged Ken McFall Jedi Master Film Handler Posts: 615 From: Haringey, London. Registered: Apr 2001 posted 04-15-2004 10:49 AM                     Peter you have him nailed in one.... The comedy of errors happened in Sctoland at an Asda store event. Two generators failed the screen fell over when it was being inflated, because someone decided to lace the screen incorrectly and the ties all got caught up etc etc.... These things really do need to be used with some intelligence. If you look at the posting from John above you can see it was done perfectly... then look at the Trafalgar Square pictures and it is clear the ballast tanks were too close and the whole thing was unstable. I have a picture somewhere of the screen actually bending over and almost touching the stage in front! The audience was constantly going ooo and ahhh as the thing was bending all over the place. Shortly after that comedy of errors I walked off another event and left them to it. Was never asked to do another one after that  |  IP: Logged Philip Borgnes Film Handler Posts: 18 From: Seattle, WA, USA Registered: Apr 2004 posted 04-27-2004 11:23 AM                        quote: Phil Blake One great portable screen is the side of a truck pantech (white one) ... I have always thought this idea of using the side of a truck would be a much better solution than an inflatable screen for many presentations. A few years ago I saw one of these advertising trucks driving around town. It isn't hard to imagine a screen in place of the ad banner. In fact you could use the truck to drive around town to advertise the event and then put it in place to screen the show. The display area size is 10' tall by 22' long.  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia. Registered: Dec 1999 posted 07-21-2004 11:44 PM                     The problem with that screen on the truck is that it's too close to the ground. Heads from the audience would encroach the image area pretty easily and would be darn annoying.  |  IP: Logged Joshua Lott Expert Film Handler Posts: 246 From: Fairbanks, AK, USA Registered: Nov 1999 posted 07-22-2004 12:52 AM                        Thomas... as per your questions on page 1. From what I understand a frame set up for that size is about $40,000 and the screen will cost you another $11,000. These are prices that I was quoted. (email me for further info.) What are you working on?  |  IP: Logged
